The original Elixrs sound good, but have a "slimy" feel that bothers me.

I tried one set of EXPs and found them to be very good strings overall - just not enough better than plain-vanilla D'addario PBs to justify 2 1/2 times the price.

I haven't tried the Nanowebs, but I hear a lot of talk about excessive breakage.

I suspect I'll go on buying the regular D'Addario PBs as cheap as I can, and change them when they seem to need it.

Just my take.

Peter.
